D - Newbie wondering about "redist" runtime size, if any

I'm evaluating "D", and wondering whether it had any "redistributable run
time" that an end-user would have to have on their system to run an
executable built with "D". If so, what size is it?

I develop freeware, and much prefer to keep the download size small. Using
mfc42.dll and msvcrt.dll, I can have significant functionality in only 50kb
to 70kb. With nsis1.98, I can have a complete MyApp_Setup.exe in only about
80kb. This is possible because I assume the end-user has Win98-FirstEdition
or later.

I gave up on Java because swing and 1.2 features depend on the 5+ meg j2re.
I shudder at C# because it assumes the end-user has the 20+ meg net
framework installed.

Does this issue apply to "D"? I compiled/linked the simple hello_world
sample program on one machine, and was able to run it on another baseline
test computer. This makes me suspect that "D" only relies on the Win32 api's
(and possibly msvcrt.dll). If an application uses Phobos, does the end-user
need some extra .dll (or two or three) on their computer?

TIA,

D generates native code (just like C/C++), so you won't need any virtual machine to run the executable.
 If an application uses Phobos, does the end-user
 need some extra .dll (or two or three) on their computer?

I don't really know, but to hazard a guess.... it wouldn't make much sense to NOT offer a statically linkable version of Phobos if it becomes the default RTL. So I assume that you won't need to distribute any DLLs if you're not using any other additional libraries. Hauke

There is no redistributable runtime dll. D programs are self-contained native executables, unless you actually code in a reference to a DLL yourself.

The fixed overhead of a D executable is on the order of 60Kb or so, any code you write goes on top of that.

D doesn't have that issue.

D does not rely on msvcrt.dll, or any other DLL's other than the regular win32 operating system DLL's that every system should have.

Win98-FirstEdition vs Win98-SecondEdition vs WinNt vs Win-2000 vs WinXp? My impression is that the core dll's may have changed, especially after Win95. Are there things to be aware of if an app should run on a Win95 computer? TIA

Usually installing IE5/IE6 in win95 updates most system dlls to win98se or so. Specially after installing DCOM98

The core dll's do change, but that doesn't affect D programs any more than it affects C or C++ programs. None of the core stuff should be affected.
